In a centralized, standardized IT environment, there is a risk of excessive dependence on a single system or a single data center. In that case, a system failure could have serious consequences for the entire Company. A number of safety mechanisms have been implemented to minimize the risk of system failure, including access control systems, emergency planning, uninterruptible power supplies for critical systems, and redundant data storage. We use firewall systems, virus scanners, etc., to protect our IT systems against data security risks resulting from unauthorized access.
